The neutrino telescope AMANDA has been set up at the geographical South Pole as first step to a neutrino telescope of the scale of one cubic kilometer, which is the canonical size for a detector sensitive to neutrinos from Active Galactic Nuclei (AGN), Gamma Ray Bursts (GRB) and Topological Defects (TD). The location and depth in which the detector is installed is given by the requirement to detect neutrinos by the Cherenkov light produced by their reaction products and to keep the background due to atmospheric muons as small as possible. However, a detector optimized for this purpose is also capable to detect the bright Cherenkov light from relativistic Monopoles and neutrino signals from regions with high gravitational potential, where WIMPS are accumulated and possibly annihilate. Both hypothetical particles might contribute to the amount of dark matter. Therefore here a report about the status of the experiment (autumn 2000) and about the status of the search for these particles with the AMANDA B10 sub-detector is given.

We report on the search for nearly vertical up-going muon neutrinos from WIMP annihilations in the center of the Earth with the AMANDA-B10 detector. The whole data sample collected in 1997, 10^9 events, has been analyzed and a final sample of 15 up-going events is found in a restricted zenith angular region where a signal from WIMP annihilations is expected. A preliminary upper limit at 90% confidence level on the annihilation rate of WIMPs in the center of the Earth is presented.
